I do layout work for eurogame publishers regularly, so I have plenty of this stuff lying around. Send me a list of what you need to symbolize, and I'll get you some from my personal stash. Seth's right in that most boardgame publishers tend to create these in-house and recycle them from project to project. The whole idea of icons is to be recognizable and universal, though, so there's little reason not to share the ones we used in Zombie Cinema, for example.
